Abstract: A block-based texture synthesis technique synthesizes an image texture that matches the textural appearance of an image texture sample. The synthesis first selects blocks of texture information from the image texture sample and places or pastes the selected blocks in different locations in each tile of the tiled image texture according to a chaos transform. The image texture sample in each tile is the background on which the selected blocks are placed. Each block contains sufficient texture information such that the transformed texture retains the continuity of visual properties, such as shape, size, and color, of the image texture sample. The synthesis can also overlay image texture samples to accomplish the synthesis.
